The present invention contains subject matter related to Japanese Patent Application JP 2004-218268 filed in the Japanese Patent Office on Jul. 27, 2004, the entire contents of which are incorporated herein by reference.
1. Field of the Invention
The present invention relates to an ejection tray that contains printed recording sheets in an image forming apparatus, to a sheet supply and ejection device for recording sheets in an image forming apparatus, to an image forming apparatus such as a printer, a copying machine, or a facsimile apparatus, and to an information display device that allows viewing of various information displayed on a display. More particularly, the present invention relates to a technique that allows information about an image that can be printed on a recording sheet to be displayed as an information image before an actual printing operation.
2. Description of the Related Art
In general image forming apparatuses, for example, printers, copying machines, and facsimile apparatuses, recording sheets, such as cut sheets, contained in a supply tray are sequentially conveyed to a printing unit, such as an ink-jet head, so that printing is performed thereon. After printing, the recording sheets are ejected and stocked in an ejection tray.
Print data used for printing on recording sheets is acquired from an information acquisition unit, such as a personal computer or a digital camera, via various interfaces (RS232C, SCSI, IEEE1394, and USB), and is stored in a memory. Printing is performed on the recording sheets according to the stored print data.
Japanese Unexamined Patent Application Publication No. 2000-36931 discloses a printer to which a digital camera serving as an information acquisition unit can be detachably connected. This printer includes a connecting base to which a digital camera is connected to acquire print data. Printing is performed on recording sheets according to the print data acquired by the connecting base.
According to the technique disclosed in this publication, images are displayed on a liquid crystal display provided on the back side of the digital camera. When any of the images is selected to be printed, print data on the selected image is transferred to the printer. A cut sheet (recording sheet) is then conveyed from a supply tray by supply rollers provided in the printer, and printing is performed thereon by a printing unit. After printing, the supply rollers are reversed to eject and stock the cut sheet in an ejection tray disposed on the supply tray.
However, images to be printed are displayed only on the liquid crystal display of the digital camera. That is, the digital camera is detached from the printer, there is no means for displaying the images. For this reason, it is possible to check what print data (image) is transferred to the printer and stored in the memory, only by actually printing the image.
It is desirable to provide an ejection tray, a sheet supply and ejection device, an image forming apparatus, and an information display device that allow information about an image that can be printed on a recording sheet to be displayed as an information image before an actual recording operation even when an information acquisition unit (e.g., a digital camera) for acquiring print data is not connected thereto, and that stores a recording sheet on which a desired image is printed by printing according to the information image.
In order to overcome the above problems, an ejection tray according to an embodiment of the present invention includes a container that contains a recording sheet printed by a printing unit of an image forming apparatus, and a cover mounted on the container. The cover has a display for displaying information, and the display displays an information image corresponding to information that can be printed on the recording sheet by the printing unit.
A sheet supply and ejection device according to another embodiment of the present invention includes a supply tray from which a recording sheet is supplied, and an ejection tray in which the recording sheet is ejected after being subjected to printing by a printing unit of an image forming apparatus. The ejection tray includes a container that contains the recording sheet after printing, a cover mounted on the container, and a display provided on the cover to display information. The display displays an information image corresponding to information that can be printed on the recording sheet.
An image forming apparatus according to a further embodiment of the present invention includes a printing unit for performing printing on a recording sheet, a supply tray from which the recording sheet is supplied, and an ejection tray in which the recording sheet is ejected after being subjected to printing by the printing unit. The ejection tray includes a container that contains the recording sheet after printing, a cover mounted on the container, and a display provided on the cover to display information. The display displays an information image corresponding to information that can be printed on the recording sheet.
An information display device according to a still further embodiment of the present invention includes a container that contains a recording sheet after printing, a cover mounted on the cover, and a display provided on the cover to display information for inspection. The display displays an information image corresponding to information that can be printed on the recording sheet by a printing unit of an image forming apparatus.
That is, in the above embodiments, an information image corresponding to information that can be printed on a recording sheet by the printing unit is displayed on the display. Therefore, the information can be checked before an actual printing operation, regardless of whether or not a means for acquiring print data is connected.
The above embodiments of the present invention can be finally applied to the same apparatus (image forming apparatus), regardless of the name. That is, the sheet supply and ejection device includes the ejection tray, and the image forming apparatus includes the sheet supply and ejection device, or includes the information display device and the printing unit.
Information acquired by an information acquisition unit, such as a digital camera, can be displayed on the display. In this case, the information acquisition unit may be placed on the cover or the display to display information. When an information holding unit is provided to hold information acquired by the information acquisition unit, the held information can be displayed. The display may have a touch panel function.
The recording sheet contained in the container can be taken out by opening the cover movably mounted on the container. Alternatively, the recording sheet may be automatically ejected from an ejection port provided in the container without opening the cover.
In the ejection tray, the sheet supply and ejection device, the image forming apparatus, and the information display device according to the embodiments of the present invention, the display is provided to display information on the cover mounted on the container that contains printed recording sheets. The display displays an information image corresponding to information that can be printed on the recording sheets by the printing unit. Therefore, even when the information acquisition unit (e.g., a digital camera) is not connected, it is possible to check the printable information before an actual printing operation. By performing printing according to the displayed information image, a recording sheet on which a desired image is printed can be contained in the container.
An embodiment of the present invention will be described below with reference to the drawings.
The ejection tray, the sheet supply and ejection device, the image forming apparatus, and the information display device of the present invention are used in the same apparatus (image forming apparatus) in the following embodiment. An ink-jet printer 10 corresponding to the image forming apparatus also corresponds to the information display device, a part (a container 13 and a cover 14) of the ink-jet printer 10 corresponds to the ejection tray, and the ejection tray and a supply tray 15 correspond to the sheet supply and ejection device.
Referring to
The ejection tray (container 13 and cover 14) is provided on the supply tray 15, and the ink-jet head 11 is provided at one end of the supply tray 15. Therefore, the ink-jet printer 10 has a planar outer shape that is one size larger than the cut sheets 12. This provides high space efficiency and excellent design.
As shown in
The ink-jet head 11 is a line head having a length correspondingly to the print width, and includes multiple heads arranged in the widthwise direction of the cut sheets 12. Therefore, it is possible to perform printing without moving the ink-jet head 11 in the widthwise direction of the cut sheets 12.
Inks of four colors, Y (yellow), M (magenta), C (cyan), and K (black) are supplied from an ink cartridge 17 to the ink-jet head 11 so that printing can be performed on the cut sheets 12 with quality of color pictures. The ink cartridge 17 is provided under the supply tray 15. That is, three components, the ink cartridge 17, the supply tray 15, and the ejection tray (container 13 and cover 14), are stacked.
Print data (for example, picture images) for cut sheets 12 is sent from an unshown digital camera (corresponding to the information acquisition unit), in a wireless manner, is received by a receiver mounted on a control board 18, and is stored in a memory (corresponding to the information holding unit). The control board 18 also controls the display of information on the cover 14 by the liquid crystal display 16. Various interfaces (RS232C, SCSI, IEEE1394, and USB) may be provided on the control board 18 for wire connection to the information acquisition unit.
After printing is performed on a cut sheet 12 by the ink-jet head 11 according to the print data stored in the memory, the cut sheet 12 is ejected in a bent form by an ejection roller, and is placed in the container 13 with its print surface facing up. Subsequently printed cut sheets 12 are stacked in the container 13.
Cut sheets 12 stacked in the container 13 can be taken out by opening the cover 14, as shown in
A cut sheet on which a desired image is printed is sometimes disposed in the lower part of a stack of cut sheets 12 in the container 13. Accordingly, the ink-jet printer 10 has sorting members 19 for sorting the cut sheets 12. The sorting members 19 are claws that are to be placed between stacked cut sheets. When the cover 14 is opened, the sorting members 19 hold, on the back side of the cover 14, all cut sheets stacked on a desired cut sheet sorted out. Therefore, the desired cut sheet is placed at the uppermost position when the cover 14 is opened, and can be easily taken out.
As shown in
As shown in
As shown in
While picture images are being sent, an image displayed on a liquid crystal display of the digital camera 20 is also displayed in a full-screen manner on the liquid crystal display 16, as shown in
The images thus sent to the ink-jet printer 10 and stored in the memory can be printed on cut sheets 12 supplied from the supply tray 15. By clicking any of the thumbnail images displayed on the liquid crystal display 16 and selecting printing, printing is performed. That is, the liquid crystal display 16 displays information images corresponding to information that can be printed on the cut sheets 12. After printing, the cut sheets 12 are stacked in the container 13.
Therefore, all images that can be printed on the cut sheet 12 can be displayed on the liquid crystal display 16, and information about these images can be checked before an actual printing operation. That is, the ink-jet printer 10 also corresponds to the information display device.
In a different display mode, the liquid crystal display 16 displays information images that have been printed on the cut sheets 12 by the ink-jet head 11. That is, displayed thumbnail images correspond to images printed on the cut sheets 12. Any of the thumbnail images may be clicked so as to be selectively displayed in a full-screen manner on the liquid crystal display 16.
In an initial state, an image displayed in a full-screen manner on a liquid crystal display 16 is allowed to be inspected, as shown in
Accordingly, for example, in order to view a favorite image with a high resolution, an image displayed on the liquid crystal display 16 is printed. For printing, any of the thumbnail images displayed on the liquid crystal display 16 is clicked. Then, the image is printed by an ink-jet head 11 (see
The printed cut sheet 12 can be taken out from a container 13 by opening a cover 14, as shown in
The ejection manner will be described in more detail. Even when a digital camera 20 (see
Simultaneously, the selected thumbnail image is printed by an ink-jet head 11 (see
In this way, information images that can be printed on a cut sheet by the ink-jet head 11 are displayed on the liquid crystal display 16 even when the digital camera 20 is not connected to the ink-jet printer 10 of this embodiment.
Therefore, information about such images can be checked before an actual recording operation.
After information is checked and printing on a cut sheet is actually performed, the printed cut sheet can be easily taken out by simply opening the cover 14. The cut sheet can also be automatically ejected from the ejection port 21 without opening the cover 14. Consequently, a cut sheet on which a desired image is printed can be efficiently taken out.
While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and the following modifications are possible:
(1) While the ink-jet printer 10 is described as an example of an image forming apparatus in the above embodiments, the present invention is also applicable to other image forming apparatuses such as printers, copying machines, and facsimile apparatuses.
(2) While the line-type ink-jet head 11 performs printing in the above embodiments, a serial ink-jet head may be used. Ink may be discharged by any method, for example, thermal discharging, electrostatic discharging, or piezoelectric discharging. Instead of the ink-jet head, for example, a thermal transfer head may be used for printing.
(3) While the liquid crystal display 16 serves as the display for displaying information in the above embodiments, it may be replaced with other displays such as an organic EL (electroluminescence) display. Information to be displayed is not limited to images, and may include, for example, characters.
(4) In the above embodiments, the liquid crystal display 16 having a touch panel function is used to display information, and selection from information images is made by a click operation. Alternatively, another display device having a touch panel function and an operating unit for selection from the information images may be provided separately.
According to the ejection tray, the sheet supply and ejection device, the image forming apparatus, and the information display device in the embodiments of the present invention, even when the information acquisition unit (e.g., a digital camera) for printing data is not connected thereto, information about images that can be printed on a recording sheet can be checked before an actual printing operation.
Therefore, a recording sheet on which a desired image is printed can be efficiently placed into the container. For this reason, the present invention is widely applicable to various ejection trays, sheet supply and ejection devices, image forming apparatuses, and information display devices.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
